$1 ECIFIGATION formingpart of Letters Patent No. 666,821, dated January 29, 1901 i Application filed September 5, 1899. Serial No. 729,530. (No model.)

To all whmn it may OOMOQWM Be it known that I, FERDINAND SOHAUB, a citizen of the United States, residing at 26 Hancock avenue, Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Musical Instruments, of which the following is a specification.

This invention relates to improvements in mechanical musical instruments, and espe cially to musical instruments of that class having a sound-producing mechanism which is operated by rotating disks having slots or projections.

The object of my invention is to provide a new and improved musical instrument of this general kind which is simple in construction, strong and durable, reliable in action, permits of changing the playing-disk at will or automatically without in any Way injuring or straining the mechanism of the instrument, and permits of rapidly and conveniently exchanging the playing-disks in the instrument for others.

In the accompanying drawings, forming a part of this specification, and in which like letters of reference indicate like parts in all the views, Figure l is a front elevation of my improved mechanical musical instrument. Fig. 2 is a central vertical transverse sectional view of the same. Fig. 3 is a horizontal sectional view of the same on the line 3 3 of Fig. 1, parts being broken away. Fig. 4 is an exterior view of the upper part of one side of the casing. Fig. 5 is a side view of the tuneindicating disk. Figs. 6. and 7 are enlarged detail side views of the two driving mechanisms and the changing mechanism, parts beiug shown in different positions in the two figures. Fig. 8 is a front elevation of the two spring-drums, the plate to which they are attached being shown in vertical section and parts being broken away. Fig. 9 is a front elevation of the automatic changing mechanism, parts being broken away.

The mechanical musical instrument is provided with a vertical metal base-plate or main plate A, which is fastened in a suitable casing or box A, of any suitable construction, and on this base-plate A the steel comb or combs B are secured in conventional manner and combined with suitable picking devices such, for example, as the well-known starwheelsand these in turn are to be operated by disks D, provided with projections or slots for operatingsaid picking devices or star-wheels, and such disks will be referred to hereinafter as note-disks. As shown, the combs B are arranged vertically on the base-plate A. The note-disks D are held vertically, in planes parallel with the base-plate, in a note-disk receptacle C, which is mount ed to swing in a horizontal plane under the combs B and base-plate A. The note-disk receptacle consists of a frame substantially in the shape of a parallelogram, composed of thefront bar C, the longer rear bar C and the two connecting end bars C which connect sleeves C secured on the front and rear bars C and C Adjacent to the inner end of each sleeve C a sleeve C is secured on each bar C and C and the two sleeves C on each bar C and C are connected by a web C. To the center of each web C a horizontal arm C is pivoted, the opposite ends of which arms C are pivoted on rods C on the inner surface of one of the side walls of the casing A, thus adapting the note-disk receptacle to swing horizontally. The two crossbars or end bars C are curved segmentally in such a manner that the convex edges face the pivotal points of the arms 0. These cross-bars have their inner edges beveled to form a support for the edges of the note-disks D, and from said cross-bars a series of U- shaped guide-frames C extend upward vertically, one leg of each frame C being secured on one cross-bar C and the other leg on the other cross-bar. The note-disks D are placed vertically between such guide-frames C which hold them in vertical position and equidistant from each other, each disk D being placed between two frames C The longer rear bar C of the note-disk receptacle C has attached to its projecting righthand end a sleeve C to which a link C is pivoted to swing horizontally, which link is provided on its free end with an eye C which can be placed upon a pin C projecting from the right-hand end of the shorter front bar C of the receptacle C, and which eye can also be placed upon a pin E, projecting laterally from the lower end of a lever E, fulcrumed at E to the plate A carrying part of the mechanism, and secured to the side of the casing A. The upper end of the lever E carries a roller E which can travel in the heart-shaped groove E of a heart-cam E secured on or made integral with a toothed wheel E secured on the inner end of a short shaft E journaled in the side plate A and carrying on its outer end, at the outer side of the casing A, a disk E which is covered by a plate or cup E having a slot E in its top part, as shown in Fig. t. The toothed wheel E has twice as many teeth E as note-disks D can be placed into the receptacle minus two. For example, if the receptacle C can hold and contain fifteen note-disks D the wheel E must have twenty-eight teeth E and the disk E has along its rim on its outer face as many equal subdivisions E as there are teeth E on the wheel E and these subdivisions are numbered,consecutively, 1, 2, 3, at, &c., from l to the right and to the left, the first and last number, which are diametrically opposite each other, appearing on ce only. The uppermost number on the disk E always shows through the slot E A short shaft F is journaled in the side plate A and on its inner end a tooth F is secured, which can engage the teeth E of the wheel E in such a manner that for each rotation of the shaft F the wheel E is rotated the distance of one tooth E. A crank-handle F is secured on the outer end of the shaft F for turning the same, and by means of it the toothed wheel E can be adjusted to bring any desired numeral on the disk E into the slot E of the plate or cup E and to move the note-disk receptacle 0 correspondingly by means of the heart-cam and lever E. The teeth E of the toothed wheel E can also be engaged by a tooth G, secured on the side of and projecting beyond the rim of a cog-wheel G, mounted on a stud G projecting laterally from the side plate A and from one side of said cog-wheel G a neck G projects, which is provided with a cam projection G". On the opposite face of the cog-wheel G a canrdisk G is formed, which is provided in its rim with acam-recess G". A lever G fulcrumed on a pin (i on the side plate A is provided on its free upper end with a triangular tooth G which fits in between the teeth E of the wheel E and can lock the latter. A helical spring I attached to the side plate A and to the free end of the lever G holds the tooth G" of the latter out of engagement with the teeth E of the cog-wheel E and presses a roller l on the lever G against the rim of the cam-disk i The cog-wheel G engages a cog-wheel H of twice the diameter of the cogwheel G and attached to the drum H of a spring-motor provided with a spring-winding cog-wheel 11 which latter is engaged by a winding-pinion H secured on the inner end of acrank-shaft II", journaled in the side plate A and provided on its outer end with a crank-handle H A spring-pressed pinion H, which acts as a noiseless automatic locking-pawl, engages the pinion H and the winding cog-wheel 11 By a train of gearing H of any well-known construction, a fan or other governor 11 of any approved construction, is driven from the cog-wheel H and is provided with the arm H which can be engaged by the arm I of the three-armed lever I, fulcrumed at I on the frame I of the governor; A helical spring I", attached to the frame I and the arm I, pulls the latter upward and presses a teeth I on the lower end of the downwardly-projecting arm I of the lever I against the pe riphery of the spring-d rum H,which drum has two holes or recesses I for receiving said tooth Iiand thus locking the drum. The arm I of the lever can be pressed upward by an L-shaped pin I projecting from a hub I on the inner end of a shaft I journaled in the side plate A and provided on its outer end with a crank-handle I which can swing over a sector-plate I on the outside of the casing A and marked at its ends Stop and S, the latter signifying Start. An L-shaped lever .I, fulcrumed at J, can alsoengage with its upper end the arm H" of the fan-governor and is pulled upward by a helical spring J attached to the upper arm J Fig. 7, of said lever J and to the frame I of the fangovernor. The lower end of the downwardlyprojecting arm J" of said lever .I is shaped as a tooth J adapted to enter notches J" in the raised rim part J of the spring-drum H, of which notches J there are two, diametrically opposite each other. A pin J projects laterally from the lower end of the arm .I of the L-shaped lever J.

Two cams K and L are attached side by side to a collar H on one end of the spring-drum H, the cam K having two long diametrically opposite cam projections K and the cam L two short diametrically opposite cam projections L. The cams K and L,with the springdrum H, turn on the pin A projecting from the side plate A.

The base-plate A is provided with two upwardly-inclined L-shaped arms M on its back, and in the upper ends of said arms the horizontal shaft M isjournaled, from which shaft two arms M extend over the top of the base plate A, of which arms one carries on its outer side a roller M which rests upon the rim of the large cam K. To the free end of each arm M a connecting-rod M is pivoted, the lower end of each of which is pivoted to a sleeve M, mounted to slide vertically on a guide-rod MZattached to and extending d ownward vertically from the base-plate A. Each sleeve M has an upwardly and inwardly inclined arm M carrying a grooved roller M in its free end. The rollers M are such a distance from each other that the note-disks D when resting upon the note-disk receptacle IIO C can swing freely between said rollers with the receptacle 0, but can lift a disk when the sleeves M are raised.

Directly below the combs B and in line with the longitudinal central line between them a note-disk support N is secured on the baseplate A and is provided with a central bore N, in which a pin N is mounted to slide longitudinally, around which pin N the notedisks D are to rotate while playing or operating the picking devices, each notedisk having a central hole D for receiving said pin N The pin N is pivoted at its inner end to a connecting-rod N the opposite end of which is pivoted to the lower end of an arm N of a rock-shaft N journaled in the arms M, at the angles of said arms. The shaft N has an upwardly-projecting arm N carrying a roller N which rests upon the rim of the cam L. The shaft N also has an upwardly-extending arm 0, to which the inner end of a connecting-rod O ispivoted, the outer end of said rod which rod passes through a guide-hole in base-plate, being pivoted to the L- shaped retaining-bar O a short distance below its upper end, which upper end is pivoted at O to an upwardly-extending bracket 0 of the base-plate. The retainingbar is pressed outward by a spring 0 attached to the bracket 0, and said retainingbar carries the usual rollers O on its downwardly-extending member and on the free end of its rectangular arm 0 carries the rollers O for pressing the edge part of the disk on the driving-wheel. A U-shaped guide-rod O for, the note-disks is pivoted at its ends 0 to the base-plate and is connected by a pivoted arm 0 to the retaining-bar O at O. A guide-rod P, slightly curved outward at its lower end, extends downward over one comb from a horizontal bracket P of the base-plate and is a short distance from the face of the comb, as shown in Fig. 2.

A second spring-drum Q is mounted on a stud O, projecting from the side plate A and carries a cog-wheel Q and is provided in the usual manner with a winding cog-wheel Q engaged by a winding-pinion Q which, as well as the winding cog-wheel, is engaged by a spring-pressed pinion Q which acts as an automatic pawl. The winding-pinion Q is secured on the inner end of a crank-shaft Q, mounted in the side plate A and provided at its outer end with a crank Q for turning it. The cogwheel Q on the springdrum Q engages a pinion R, mounted on a stud R of the side plate A and united with a cog-wheel R which engages and drives a train of gearing R which operates a fan or governor R of any well-known construction. The cogavheel R also engages a pinion R formed on one end of a sleeve R mounted oh a stud I of the side plate A and on the opposite end of this sleeve is formed a pinion R, which engages a cog-wheel R Fig. 9, pivotally mounted on the side of a lever S, fulcrumed, by means of its arms S, on the stud R and the cog-wheel R engages a pinion R flmade integral with a toothed disk driving-wheel R mounted to turn on the arm S of the lever S. The toothed wheel R is adapted to engage holes or teeth formed along the rim of the note-disk D for the purpose of rotating such disk from the rim. Ahelical spring S has one end attached to the side plate A and the other end to the upper end of the lever S and presses said lever against a roller 8* on the lower end of a lever T, fulcrumed on the stud G and provided at its upperend witharoller T, which bears against the neck G on the cog-wheel G. A pin T extends upward from the upperend of the leverT and can act on the laterally-projecting pin J on the arm J of the L-shaped lever J. The lower end of the lever T is shaped as a tooth T which can enter notches T in the raised rim T of the spring-drum Q,of which notches T 'there are two, diametrically opposite each other. The lever S has a laterally-prqiecting arm U, which can be engaged by the arms U and U of a short shaft U mounted in the side plate A and provided at its outer end with a crankhandle U for turning it, which crank-handle can swing over a sector-plate U on the outside of the casing A, which sector-plate is marked at one end O,signifying Change, and at the other end B, signifying Repeat. The shaft U is provided with a third arm U, which can be tripped when in a certain position by two diametrically opposite pins U on one end of the spring-drum Q.

The base-plate A is provided with a vertical slot V, through which the toothed driving-wheel R can move in the direction from front to rear of the base-plate, as indicated by full and dotted lines in Figs. 6 and 7. At each end of this slot V a horizontally outwardly projecting pin V is fastened on the base-plate, and each pin carries on its outer end a roller V upon which the note-disk D can rest while rotating and playing.

The lever S has an angular downwardlyextending arm W, whichcan engage the arm or pin W of the fan or governor R The cross-bars O of the note-disk receptacle C are curved segmentally, so that the distance from the plane of the pivots of the carriage to said bars is smallest at the central line of the carriage and greatest at the front and rear of the carriage. It is evident that if these bars were made straight the central disks would be the proper distance from the pivots when the center of the carriage is vertically below the comb; but if such carriage were swung to the front or rear it is evident that the front and rear disks would swing in the arc of a circle, and thereby as they approached the center would be moved a greater distance from the plane through the pivots, and hence would not be in proper position for elevating. culty that these bars are curved, so that when the front and rear disks arrive in vertical position below the combs they will not be shifted It is to avoidthiadifii laterally, but will have precisely the same position that the middle disks had.

The operation is as follows: To place the note-disks D into the receptacle C, the eye C on the front end of the link 0 is moved off the pin Eon the lower end of the leverEand placed upon the pin C on the front righthand corner of the note-disk receptacle 0, as shown in dotted lines in Fig. 2, and now the receptacle 0 can readily be swung to the front of the casing A and the note-disks in the same removed and replaced by others. The receptacle O is then swung back into the casing A and the link C is again engaged with the pi n E on the lowerend of the lever E. To start the in strument,the crank-handle P is shifted downward and to the right, Fig. 4, and thereby the pin 1 is moved upward to the right, Fig. 6, and raises the arm 1 of the lever I, whereby the arm I of this lever is forced down and releases the fan or governor H and at the same time the tooth 1 on the lower end of the arm I of the lever I is lifted out of the hole I in the spring-drum H, and the latter is thus free to rotate in the direction of its arrow, Fig. 6, under the action of its spring and rotates the cams K and L and the cog-wheel G. As soon as the wheel G begins to rotate the cam G by acting on the roller F of the lever G forces the tooth G on said lever G in between two teeth E of the wheel E thus locking this wheel, the heart-cam E the lever E, and the note-disk receptacle 0 positively and reliably in place, and thus for the time being preventing any and all movements of such locked parts. One cam-wing K acting on the roller M on the one arm M lifts the same,and thereby the sleeves M are raised on the guide-rods Mfland in theirupward movement the grooved rollers M encounter the edge of the note-disk D directly above them, whereby said disk is lifted vertically, being guided by the guideframes 0 By the time the said note-disk has been raised so high that its central hole D registers with the bore of the support N the roller M on the arm M travels on a concentric part of the cam edge and the disk D is raised no farther. The disk D is also guided by the rod P,which prevents accidental movement away from the combs B, and by the U- shaped guide-rod O, which prevents the projections on the disk D from striking against the pickers or the comb-tongues and damaging any of these parts. As the upper part of the rising disk is guided between said rods P and 0 it is conducted into the proper position without mutilating any parts. By this time the cam L by acting on the roller N on the end of the arm N has pushed the pin N into the hole D in the center of the disk D and by means of the arm 0 of the rock-shaft N and the connecting-link O has pressed the retaining bar 0 against the action of its spring upon the raised disk and pressed the same against the rollers V and other supporting-rollers as are usually provided in instruments of this kind. As the retaining-bar swings toward the combs it also swings the U shaped guide'bar 0 toward the main plate A by means of the pivoted arm 0 so that this guide-bar clears the projections on the inner side of the note-disk. A short time before this the cam projection G on the neck G of the toothed wheel G has pressed the upper end of the lever T to the left, Fig. 7, causing the lower end of said lever T to press the upper end of the lever S to the right, Fig. 6, whereby the arm W on the lower end of the lever S is raised and disengaged from the arm W of the governor R As the tooth T has been moved out of the recess T in the raised rim of the spring-drum Q, the latter is released and is turned by its spring and rotates the driving-wheel R by means of the intermediate gearing described. By the movement of the upper end of the lever S to the right the driving-wheel R has been moved from the position shown in full lines in Fig. 6 to the position shown in dotted lines and can thus engage the teeth or holes in the rim part of the note-disk that has just been raised and mounted on the central pin N and thus rotates this disk, and the teeth or slots of the same operate the musiccomb pickers. By the movement of the upper end of the lever T to the left the pin T has been moved away from the pin J 8 on the arm J 4 of the angle-lever J, and when a notch or recess J G of the spring-drum H arrives at the tooth J the spring J throws the said tooth J on the end of the arm J into this notch, and at the same time the upper arm J 3 of the lever J is thrown upward and engages the arm H of the governor 1-1 thus locking the latter. It is thus evident that after the spring-drum H and the mechanism connected therewith have raised a note-disk and mounted the same in place the said drum is locked, while the drum for operating the sound-producing mechanism is rotated, having been started a short time before the drum H was stopped. When the drum Q has made halt a turn, the spring S presses the tooth T into a notch T", whereby the arm TV is moved downward and stops the governor R", and the driving-wheel R? is moved from the position shown in dotted lines in Figs. 6 and 7 into the position shown in full lines in Fig. 6, it being understood that the means for changing or repeating a tune have not been considered. By the movements just described of the lever T the angle-lever J is disengaged from the drum H and governor H and the mechanism for changing the tunedisks is thus started. The cam wing or projection L passes oif the roller N on the arm N permitting the spring 0 to throw the retaining-bar O outward, whereby the pin N is withdrawn from the disk and the roller M of the arm M passes off the end of the camwing K and slides down the concave edge of said wing, permitting the note-disk D that has been rotated to descend with the sleeves M supporting it. By the time this note-disk has arrived on the note-disk receptacle 0 the recess G 01 the cam G on the wheel G has arrived at the roller F of the lever G permitting the spring F to move said lever to the left, whereby the tooth G9 is temporarily disengaged from the wheel G, and immediately thereafter the tooth G on said wheel G turns this wheel E the distance of one tooth, and by means of the heart-cam E and lever E the note-disk receptacle 0 is moved forward or backward the distance of one disk. By that time the other end of the recess G has arrived at the roller F on the lever G and presses the same to the right, whereby the tooth G is again engaged with the teeth of the wheel E and locks the latter. Then a cam-wing K begins to act on the arms M which are raised, and the note-disk D, which has just been shifted into position over the rollers M is raised and mounted in proper position for playing, as previously described, and then the disk-rotating mechanism is started automatically again, and a short time thereafter the disk elevating and lowering mechanism is locked, and so on. When it is desired to stop playing, the lever I is moved to Stop on the sector-plate, whereby the pin 1 is brought into the position shown in full lines in Fig. 6, permitting the tooth I on the arm I of the lever I to snap into a hole I in the drum H when said hole arrives at said tooth I and at the same time the free end of the arm I snaps upward, engages the arm H of the governor H and locks the latter.

If the note-disks are to be changed after having played once in the manner just described, the handle U must be shifted to the letter O on the sector-plate U Fig. 4, whereby the arms U, U and U on the short shaft U are moved into the position shown in Figs. 6 and 7, and the arm U, by engaging the arm U of the lever S, holds the latter and the parts thereon in the position shown in Fig. 7. The pins U on the drum Q strike against the arm U and throw the arm U up ward and off the arm U of the lever S, permitting the spring S to throw the tooth T of the lever T into the notch T of the drum Q, and thus stop the playing mechanism and start the note-disk elevating and lowering mechanism in the manner described, and so on. The arm Uis so heavy that it drops sufficiently to engage the arm U when the latter has been moved to the right, Fig. 6, beyond the end of the arm U, thus temporarily locking the lever S in place. On the other hand, when it is desired to repeat a melody indefinitely the crank-handle U is turned to R on the sector-plate U Fig. 4, whereby the arm U is brought into the position shown in Fig. 4 and engages the arm U of the lever S and holds the latter and the parts thereon and the lever T permanently in the positions shown in Fig. 7, thus leaving the playing mechanism free to operate an indefinite time and keeping the disk-changing mechanism locked. With the arm U in this position the motor of the disk-changing mechanism is released the tooth G is engaged with the wheel E and locks the latter in place until the disk that has been raised is brought back into its original position in the note-disk receptacle.
